Step-by-Step Configuration Procedure
Instructions on the 3rd Party Solution
This setup guide will show you how to forward your Auditbeat logs to Sekoia.io by means of a syslog transport channel.
Install and Configure Auditbeat
- To download and install Auditbeat on a Debian-based distribution (including Ubuntu, Linux Mint, etc.):
curl -L -O https://artifacts.elastic.co/downloads/beats/auditbeat/auditbeat-8.11.4-amd64.deb
sudo dpkg -i auditbeat-8.11.4-amd64.deb
- To download and install Auditbeat on Fedora, CentOS, or Red Hat Enterprise Linux:
curl -L -O https://artifacts.elastic.co/downloads/beats/auditbeat/auditbeat-8.11.4-x86_64.rpm
sudo rpm -vi auditbeat-8.11.4-x86_64.rpm
Modify the version number with the newest one.
- Replace the configuration file
/etc/auditbeat/auditbeat.yml
with the following content:

- Ensure the permissions for the new
auditbeat.yml
are correct:
sudo chmod 0600 auditbeat.yml
sudo chown root:root auditbeat.yml
- Load the predefined assets for parsing, indexing, and visualizing your data:
sudo auditbeat -e
- Start Auditbeat:
sudo systemctl restart auditbeat.service
Configure Local Rsyslog Service
- Install rsyslog if it's not already installed:
sudo apt install rsyslog
- Edit the
/etc/rsyslog.conf
file for a light client rsyslog setup:
module(load="imuxsock") # provides support for local system logging
module(load="imklog" permitnonkernelfacility="on") # provides kernel logging support
$MaxMessageSize 20k
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat

$ActionQueueSaveOnShutdown on
$ActionResumeRetryCount -1
$WorkDirectory /var/spool/rsyslog
$IncludeConfig /etc/rsyslog.d/*.conf
*.* -/var/log/syslog
- Add a dedicated configuration file for Auditbeat logs in
/etc/rsyslog.d/8-linux_auditbeat.conf
:
module(load="imfile" PollingInterval="10")
input(type="imfile"
File="/var/log/auditbeat/auditbeat*.ndjson"
Tag="linux_auditbeat"
Severity="info"
Facility="local7"
ruleset="auditbeatSekoia"
addMetadata="on"
)
ruleset(name="auditbeatSekoia") {
if (re_match($!metadata!filename, "auditbeat-[0-9]{8}(-[0-9]*)?.ndjson")) then {
action(
type="omfwd"
protocol="tcp"
target="YOUR_RSYSLOG_DESTINATION_SERVER"
port="514"
TCP_Framing="octet-counted"
)
}
}
- Ensure the destination server in the rsyslog config is correctly set:
sudo systemctl restart rsyslog.service
Note
If you encounter any issues during the configuration specified in this section "Instructions on the 3rd Party Solution," please do not hesitate to contact your editor. We also welcome any suggestions for improving our documentation to better serve your needs.
Instruction on Sekoia
Configure Your Intake
This section will guide you through creating the intake object in Sekoia, which provides a unique identifier called the "Intake key." The Intake key is essential for later configuration, as it references the Community, Entity, and Parser (Intake Format) used when receiving raw events on Sekoia.
- Go to the Sekoia Intake page.
- Click on the
+ New Intake
button at the top right of the page. - Search for your Intake by the product name in the search bar.
- Give it a Name and associate it with an Entity (and a Community if using multi-tenant mode).
- Click on
Create
. - You will be redirected to the Intake listing page, where you will find a new line with the name you gave to the Intake.
Note
For more details on how to use the Intake page and to find the Intake key you just created, refer to this documentation.
Configure a forwarder
To forward events using syslog to Sekoia.io, you need to update the syslog header with the intake key you previously created. Here is an example of your message before the forwarder
<%pri%>1 %timestamp:::date-rfc3339% %hostname% %app-name% %procid% LOG RAW_MESSAGE
<%pri%>1 %timestamp:::date-rfc3339% %hostname% %app-name% %procid% LOG [SEKOIA@53288 intake_key=\"YOUR_INTAKE_KEY\"] RAW_MESSAGE
To achieve this you can:
- Use the Sekoia.io forwarder which is the official supported way to collect data using the syslog protocol in Sekoia.io. In charge of centralizing data coming from many equipments/sources and forwarding them to Sekoia.io with the apporpriated format, it is a prepackaged option. You only have to provide your intake key as parameter.
- Use your own Syslog service instance. Maybe you already have an intance of one of these components on your side and want to reuse it in order to centralize data before forwarding them to Sekoia.io. When using this mode, you have to configure and maintain your component in order to respect the expected Sekoia.io format.
Warning
Only the Sekoia.io forwarder is officially supported. Other options are documented for reference purposes but do not have official support.
Raw Events Samples
In this section, you will find examples of raw logs as generated natively by the source. These examples are provided to help integrators understand the data format before ingestion into Sekoia.io. It is crucial for setting up the correct parsing stages and ensuring that all relevant information is captured.

TOR Usage Generic Rule
Detects TOR usage globally, whether the IP is a destination or source. TOR is short for The Onion Router, and it gets its name from how it works. TOR intercepts the network traffic from one or more apps on user’s computer, usually the user web browser, and shuffles it through a number of randomly-chosen computers before passing it on to its destination. This disguises user location, and makes it harder for servers to pick him/her out on repeat visits, or to tie together separate visits to different sites, this making tracking and surveillance more difficult. Before a network packet starts its journey, user’s computer chooses a random list of relays and repeatedly encrypts the data in multiple layers, like an onion. Each relay knows only enough to strip off the outermost layer of encryption, before passing what’s left on to the next relay in the list.
